Timing Product Concentration Chemical Thinning Petal Fall to 5-7 days after petal fall Rate of Formulated Product Amid-Thin W ppm 4-8 oz/100 gal For thinning Bartlett and Bosc. Apply at petal fall or within 5-7 days after petal fall days after full bloom Fruitone-N or Fruitone-L ppm 4-6 oz/100 gal Directions for use on Bartlett and Bosc pears. NAA is more effective at early timings and should be applied as soon as fruit set is apparent for greatest success. Late applications may result in reduced fruit size. Do not apply when temperature is below 60 F or above 85 F. NAA will not usually adequately thin Bartlett, but the addition of a surfactant will improve thinning. Fruit Size 8-14 mm(7-28 days after full bloom) Maxcel, RiteWay ppm 4-6 oz/100 gal Do not apply when temperature is below 60 F or above 85 F.

10 188 CHAPTER 12 GENERAL PEST MANAGEMENT CONSIDERATIONS PEARS Table Growth Regulator Uses in Pears. Timing Product Concentration Rate of Formulated Product Induction of Lateral Branching in Young Trees 1-2 of terminal shoot growth Promalin, Perlan, Typy ppm pt/5 gal Include a non-ionic surfactant and apply as a directed spray to areas where additional branching is desired. This practice is more effective in the second and third growing seasons after planting. Response on weak or low-vigor trees is usually disappointing. For nursery stock treat after trees have reached a terminal height at which lateral branching is desired. Preharvest Fruit Drop Control 1-2 weeks before anticipated ReTain harvest 0.74 lb/acre or 333 g/acre or (1 pouch) Apply in sufficient water to ensure thorough but not excessive coverage. An organosilicone surfactant (12 oz/100 gal) must be used with ReTain. 5-7 days before harvest Fruitone-N 10-15ppm 4-6 oz /100 gal Apply 7 days before harvest on D Anjou, Bosc, and Bartlett. Make separate sprays to early and late maturing varieties. * To convert ounces to grams multiply ounces by To convert fluid ounces to milliliters multiply fluid ounces by
